Effect of Different Growing Periods on Yield and Quality Characteristics in Artichoke (Cynara cardunculus var. scolymus) Production

The present study was carried out to determine the performance of artichoke as an alternative vegetable crop in Konya's ecological conditions. Thus, Jade F1 (JD) and Bayrampaşa (BP) cultivars were planted for 2 planting periods (1st - May 20 and 2nd - June 10) and some growth characteristics, yield characteristics, and head characteristics were investigated. BP planted on 2nd period and the JD planted on 1st period produced remarkable stem development. BP had higher plant height values than JD and reached the highest plant height values with the increase in air temperature. BP and JD well adapted to the field conditions as the temperature increased and they had a relatively higher leaf number. The maximum stalk number with head per plant was determined as 10.65 in 2nd planting period and the JD had the highest total head number per decare (da) in 1st planting period with 7850 heads. Likewise, the average head number and total head weight with stalk were the highest with 7.85 per plant and 1613 kg da-1 in the 1st period in JD, respectively. JD had the highest head diameter (9.15 cm) in 2nd period, followed by JD (8.10 cm) and BP (7.40 cm) in 1st period. JD plants had the highest heads (9.36 cm) and the highest calycle diameters (9.93 cm) in the 2nd period. Eventually, comparative economic analysis was realized with tomato production, and the 1st planting period with JD was determined to be feasible in Konya conditions.
